Abstract: What is the impact on human capital investment when a worker's ability and investments are observed by the labour market only when the worker invests in self-promoting activities? When firms pay spot market wages, high ability workers overinvest in self- promotion. There is no employment contract that attains full efficiency. Constrained efficiency is attained when employment bonds are feasible. \ The contract that both attains constrained efficiency and minimizes the bond posted offers (i) severance payments, (ii) strategically matching outside offers and (iii) a minimum wage.
